Two possibilities exist: either we are alone in the Universe... - Arthur C. Clarke

"How inappropriate to call this planet "Earth,"when it is clearly "Ocean."

"The only way to discover the limits of the possible is to go beyond them into the impossible."

"Magic's just science that we don't understand yet."

"There is no reason to assume that the universe has the slightest interest in intelligence—or even in life. Both may be random accidental by-products of its operations like the beautiful patterns on a butterfly's wings. The insect would fly just as well without them."

"I'm sure the universe is full of intelligent life. It's just been too intelligent to come here."
